Banana Cake with Salted Caramel Frosting

Salted Caramel Sauce is a Must

Salted caramel has long been one of my favorite treat of mine and what makes it so special really is the salt.

Last December I had the opportunity to attend Morton Salt’s Next Door Chef event in New Orleans along with several other guests. It was such a fun dinner experience where they converted someones home into an actual pop-up restaurant for a day.

Acclaimed chef Nina Compton coached a home cook and then this cook prepared an incredible meal for us in which different types of Morton salt were used.

At the event we tried a number of inspiring dishes where we could taste how different types of salt transformed each dish, from appetizer and drinks, to side dish, to the main dish and then onto dessert.

Of course, my favorite part of the meal was the Coconut Caramel Budino with Grilled Mangos and Morton Kosher Salt which was served for dessert. I just love the way the salt really highlighted that dessert and it does just the same here!

The dinner was so inspiring! I couldn’t say a negative thing about anything I tried. And part of the reason it was all so good was that it was properly seasoned with salt.

Salt makes a world of difference in everything we cook and bake. It can drastically change the end result. Can you imagine a world of food without salt??

  • Banana Cake recipe see notes

Caramel sauce

  • 1 cup (210g) granulated sugar
  • 1/4 cup water
  • 3/4 tsp Morton Fine Sea Salt
  • 1/4 cup (56g) unsalted butter, diced into 1 Tbsp pieces
  • 2/3 cup (160ml) heavy cream
  • 2 pinches Morton Coarse Sea Salt, for topping


  • 3/4 cup (170g) unsalted butter
  • 3 cups (390g) (360g) powdered sugar
  • 1 tsp vanilla extract
  • 1/2 cup caramel sauce (from above)
  • 1/2 cup chopped pecans or walnuts, for garnish (optional)
  • 2 bananas, diced, for topping (optional)
  • Semi-sweet chocolate shavings, for garnish (optional)


  • Prepare banana cake as directed and let cool completely. Meanwhile prepare the caramel sauce.
  • For the caramel sauce: have all caramel ingredients ready. In a medium saucepan combine sugar, water and sea salt. 
  • Set over medium-high heat and whisk constantly until it begins to boil, then allow mixture to boil until it turns to a rich amber color, carefully swirling pan occasionally. 
  • Immediately whisk in butter then remove from heat and whisk in cream (be careful, it will steam! A long handled whisk is recommend) and stir until smooth. 
  • Allow to cool several minutes then pour into a glass bowl or jar and chill caramel until completely cooled.
  • For the frosting: whip butter until light and fluffy. Add powdered sugar, 1/2 cup of the cooled caramel sauce, sea salt and vanilla.
  • Mix until well combined and slightly fluffy. Chill until it becomes a more firm consistency if needed.
  • To assemble cake: spread about half of the frosting over first layer of cake then drizzle and spread a fair spoonful of the caramel sauce over the frosting. 
  • Top with the second layer of cake then add remaining frosting. Just before serving top with the bananas* and nuts, then drizzle over remaining caramel sauce, sprinkle with shaved chocolate and coarse sea salt.


  • Follow link HERE for the recipe for the banana cake. Only make the cake portion.
  • *To slow browning of the bananas if needed, you can soak them in a lemon water solution for about 1 minute. Just add 1 Tbsp lemon juice to about 1 cup of water then dry slightly on paper towels.

Incredible chef Nina Compton and myself.

      A week ahead is fine, just store in the fridge then bring to room temp.

    Thanks for sharing this recipe! Didn’t have buttermilk nor whole milk so I swapped it with yogurt. The cake itself was very delicate and moist. Not overtly sweet. The buttercream and caramel are a great match for the banana. Almost like a bannoffee pie. :)

    Hi, J. What would be the subsitutes/additions for making this cake Gluten free?? Tks!

    • Jaclyn

      I haven’t tested it gluten-free yet so I couldn’t say for sure. I wonder if a 1:1 gluten free blend would work in place of the flour here.

    i baked the cake and it didn’t grow at all and was really pale. i baked it for 50 minutes and used a smaller pan and i think it was cooked through it was just really small and tough, bad consistency and looked like a sad pancake. any ideas why that happened?

      It almost sounds like the baking soda was accidentally forgotten or old? Sorry to hear that happened!

  • Grace

    The cake was a hit!!!! Thank you. I made this for a friend’s birthday.. the banana cake you suggested and it came out beautifully. Thank you again for sharing this. It is a keeper!

  • Naomi

    Hi, how long does the cake stay fresh for? Do the bananas on top stay good?
    Thanks x

      Cake should keep well in the fridge for 4 or 5 days, the banana slices should only be added right before serving as they will brown.

    Made this for my mums bday. Often fail at baking but was able to follow this succesfully. Cakes were moist. Caramel sauce was yummy. Didn’t particularly enjoy the frosting though, not smooth and quite sweet. Thanks for the recipe for this simple impressive cake
